Sound Changes II

The concert continued without issues until the second to last song: Starry Sunrise. Umi's microphone suddenly stopped working during her section of the song. Fortunately, Aki quickly realized what was happening and sang for her since they both had a similar vocal range.

I approached Miki again. "What happened?"

"I'm not sure, her microphone just stopped working. She probably doesn't hear us either."

"There are more microphones, right?"

"Yes, in that box," he answered and pointed at a box on the desk.

I opened it and grabbed one of the three microphones. "The song will finish in two minutes, then the girls are going to give a short speech to introduce the last song. We'll swap at that moment."

"Sure, but we can't give instructions to Umi."

"Just tell the rest of the girls when they aren't singing. I'll stand on the stairs with the microphone. Umi will see me."

"Understood."
